Step-by-step explanation:

20 men work 8 hours a day for 18 days.

that are

20×8×18 = 2880 work hours to complete that work.

if 24 men work 5 hours a day, that are

24×5 = 120 work hours per day.

we still need to do the total 2880 work hours.

so, they will need

2880 / 120 = 24 days to complete the work.

12 grapes cost 90 $how many can bought in 40$
likoan [24]

Let x = the amount of grapes that can be bought for 0.40.


Note: By 90 I assume you mean 90 cents. The same for 40.


12/x = 0.90/0.40


0.90x = 12(0.40)


0.90x = 4.80


x = 4.80 ÷ 0.90


x = 5.33333


We can round the decimal to the ones place to get 5 grapes.

Which of the numbers below are whole numbers A 0.328 B.678.79 C.159113 D.3809 E.757 F.0​
Naily [24]

Answer:

F

Step-by-step explanation:

F

zero

Anytime you have zero as a possible answer, you have to consider it carefully. Part of the whole number system is 0. They go up from there. No fraction is a whole number. No decimal is a whole number except those that are equal to  a whole number.

The rest are all decimals so they are not whole numbers. Note I just noticed that the other numbers have periods after the choice. There are other whole numbers there if that is the case.

C D E and F are all whole numbers if that is a period after their choice letters.
